LC897127K

Ordering number : ENN6251 CMOS IC LC897127K SCSI CD-ROM Decoder with On-Chip DVD Interface Overview The LC897127K is a CD-ROM decoder that includes an on-chip DVD interface. Since the LC897127K also includes an on-chip SCSI interface, it can be used to implement a SCSI-compatible DVD-ROM drive simply by combining it with a DVD decoder. It can also operate as an independent SPC functional unit.
